Many interesting theories here. I tend to agree with a previous post on this topic, that is,.. the mind is very powerful and not completely understood, thats a good starting piont. With that said, I also believe that an individuals emotional state can often alter ones surroundings, such as losing a loved one or a lifestyle,etc. To experience great emotional trauma. I believe that during these times an individual is in a heighted state of consciousness and projecting a much greater energy which perhaps will make him or her more receptive to these occurrences that would normally not be noticed. Thats my take on this topic.
